This is a copy of a draft report produced by the U.S. Central Intelligence Agency (CIA) in the mid-1970s on the 1953 Coup d'etat in Iran, titled "The Battle for Iran." The document's Foreward describes the report as an "account of the role of the Central Intelligence Agency in the political action operation that altered the course of history in Iran... It is based on files remaining in the [CIA Near East] Division (although the great bulk of the correspondence and traffic dealing with the operation was destroyed in 1962), on the draft history written in 1954 by Dr. [Redacted-- Donald N. Wilber], on personal interviews with a number of active and retired Agency officers who participated in the action, on Central Reference Service personality files, and on a variety of open sources."
This particular copy of the report was declassified in 2014 in response to a Mandatory Declassification Review request from the National Security Archive (NSA) at George Washington University. The NSA released this document online here in June of 2014, along with previously declassified versions released in 1981 and 2011: http://www2.gwu.edu/~nsarchiv/NSAEBB/NSAEBB476/.
In the document's release notes, the National Security Archive stated that "As a rough approximation, about 40 of the 150 pages include some amount of newly released material, sometimes the better part of a page, at other times only a few words. Most of the released text is in Sections III, IV and V, with about two-and-a-half pages newly available in Appendix D. Unaccountably, Appendix E, a chronology of events, has been withheld in its entirety. The remaining excisions are too extensive to allow a thorough evaluation of the document..."
